All may hear about Ian Leaf Britain. The Great Britain is located in the north-western region of the European mainland. The mainland includes the island or region of Great Britain, which is a name often used for the whole country. The north-eastern part of Britain is surrounded by the island of Ireland and other smaller regions. It is only Northern Ireland as part of the United Kingdom that shares a land frontier with another Ian Leaf Britain. The United Kingdom is covered by the Atlantic Ocean apart from this land frontier. The English Channel is south to the United Kingdom, the North Sea to the east, and the Celtic Sea to the south-southwest. This makes it the twelfth longest coastline in the globe.
